Pattern Editor Area
Use the Pattern Editor area to define a pattern that searches data for matches based on a dataset and any additional constraints (sub-rules or checkpoints) within the pattern.
Figure 8-4 Rule Scenario Editor - Pattern Editor Area

In the Pattern Editor area, you can define the elements of a primary rule, sub-rules, and checkpoints that create the rule pattern.
The Pattern Editor area contains the following elements:
- Primary Rule: Identifies the initial filter within a pattern; only one primary rule per rule pattern is allowed (refer to Primary Rule, for more information).
- Sub-Rules: Defines additional pattern elements that apply to matches that the primary rule detects. You can apply many sub-rules to a rule pattern; sub-rules are optional (refer to Sub- Rules, for more information).
- Checkpoints: Enables you to add additional constraints that must be satisfied to generate a match. Checkpoints evaluate variables captured in the primary rule or a sub-rule. A checkpoint does not have a dataset associated with it, and checkpoints are optional (refer to Checkpoints, for more information).
